Development of the integration of postprocessor for five-axis machine tools
2012 IEEE/ASME International Conference on Advanced Intelligent Mechatronics (AIM), 2012A postprocessor capable of converting the cutter location data to machine control data is the important interface between the NC programming design and the manufacture. Owing to the fact that multi-axis NC data can only be applied to the specified machine tool configuration and various combinations may be synthesized to multi-axis machine tool ...

Planning of tool orientation for five-axis cavity machining
The International Journal of Advanced Manufacturing Technology, 2003This study examines the feasibility of using open regions and vector fields to determine the appropriate tool orientation in five-axis NC machining of cavity regions with undercut areas. The first step involves slicing the to-be-machined surface into thin layers and then comparing those layers to find the position of the undercut; that is, the position

Smooth trajectory generation for five-axis machine tools
International Journal of Machine Tools and Manufacture, 2013Abstract This paper presents a smooth spline interpolation technique for five-axis machining of sculptured surfaces. The tool tip and orientation locations generated by the CAM system are first fitted to quintic splines independently to achieve geometric jerk continuity while decoupling the relative changes in position and orientation of the cutter ...

Five-Axis Machining Tool Vector Control of Impeller
Key Engineering Materials, 2009There are two key problems in the manufacture process of impeller, one is the collision of tool and blade, the other is gnawed-cutting arisen by non-uniform change of the cutter axis. UG software was used to solve those problems. Tool tip position was solved by UG. The control algorithm of collision-free cutter-axis was described and applied.

Local toolpath smoothing for five-axis machine tools
International Journal of Machine Tools and Manufacture, 2015Abstract When five axis CNC machine tools follow series linear toolpath segments, the drives experience velocity, acceleration and jerk discontinuities at the block transition points. The discontinuities result in fluctuations on machine tool motions which lead to poor surface quality.

A Machining Test to Reflect Dynamic Machining Accuracy of Five-Axis Machine Tools
Advanced Materials Research, 2012NAS (National Aerospace Standard) 979 is the only standard well known in industry describing a five-axis machining test for measuring kinematic errors of five-axis machine tools. As it cannot reflect the tool path characteristics of typical ruled surface machining, five-axis machine tools which passed the NAS test may not have the ability to satisfy ...

Five-axis CNC machine tool contour error control method
Proceedings of the 2019 International Conference on Robotics, Intelligent Control and Artificial Intelligence, 2019In the five-axis CNC machining, various errors caused by factors such as geometrical accuracy and dynamic characteristics of the machine tool will eventually appear as the contour error of the part. Therefore, controlling and compensating for contour errors is of great significance.
